    Api: Api;

Implementations

impl<UD, K: Kind, Api: Api, const REM: bool> MenuItem<K, UD, Api, REM>

pub fn title(&self) -> Cow<'_, str>

Gets the display title of the menu item.

Returns sys::ffi::playdate_sys::getMenuItemTitle

pub fn set_title<S: AsRef<str>>(&self, title: S) -> Result<(), NulError>

Sets the display title of the menu item.

Returns sys::ffi::playdate_sys::setMenuItemTitle

pub fn get_userdata(&self) -> Option<&mut UD>

pub fn set_userdata(&self, userdata: UD) -> Option<UD>

Set userdata, replace and return old userdata.

pub fn value(&self) -> c_int

Gets the integer value of the menu item.

See also MenuItem::set_value.

Equivalent to sys::ffi::playdate_sys::getMenuItemValue

pub fn set_value(&self, value: c_int)

Sets the integer value of the menu item.

For checkmark menu items (CheckMenuItem), 1 means checked, 0 unchecked.

For option menu items (OptionsMenuItem), the value indicates the array index of the currently selected option.

See also CheckMenuItem::is_checked, OptionsMenuItem::selected_option.

Equivalent to sys::ffi::playdate_sys::setMenuItemValue

Equivalent to sys::ffi::playdate_sys::getMenuItemValue

impl<UD, Api: Api, const REM: bool> MenuItem<Options, UD, Api, REM>

pub fn selected_option(&self) -> i32

The array index of the currently selected option.

Equivalent to sys::ffi::playdate_sys::getMenuItemValue

pub fn remove(self) -> Option<UD>

Trait Implementations

impl<Kind, UserData, Api, const REMOVE_ON_DROP: bool> Debug for MenuItem<Kind, UserData, Api, REMOVE_ON_DROP>

where Kind: Kind + Debug, UserData: Into<Box<UserData>> + Debug, Api: Api + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<UD, K: Kind, Api: Api, const REM: bool> Drop for MenuItem<K, UD, Api, REM>

fn drop(&mut self)

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
